Es sind bereits Prägepressen bekannt, bei denen das Einfärben des Stempels in der Weise geschieht, daß die Färbevorrichtung und die Wischvorrichtung zum Entfernen der überschüssigen Farbe des Stempels auf einem Wagen angebracht sind, der unter dem Stempel hin und her bewegt wird. Dabei muß der Wagen immer einen Leergang und einen Arbeitsgang ausführen, den Leergang, um dieEmbossing presses are already known in which the inking of the stamp in the Way happens that the staining device and the wiping device to remove the excess ink of the stamp is placed on a carriage that is under the stamp is moved back and forth. The car must always carry out an empty run and an operation, the empty run around the

ίο Färbe- und die Wischvorrichtung unter den Stempel zu bringen, und den Arbeitsgang zum Einfärben und Abwischen des Stempels. Während des Leerganges des Wagens steht der Stempel wie beim Arbeitsgang ebenfalls still. Hierdurch wird die Leistungsfähigkeit der Maschine beeinträchtigt. Bei der Vorrichtung nach der vorliegenden Erfindung ist dieser Nachteil dadurch vermieden, daß der Träger der Färbe- und der Wischvorrichtung eine kreisende Bewegung ausführt, wobei die Einfärbebürste während ihrer Tätigkeit in achsialer Richtung hin und her geschoben wird. Ein Leergang, währenddessen der Stempel untätig verbleiben muß, ist somit vermieden. Unter sonst gleichen Arbeitsbedingungen würde eine mit der Vorrichtung nach der vorliegenden Erfindung ausgerüstete Maschine eine doppelt so große Leistung vollbringen als die mit den bereits bekannten Vorrichtungen versehenen Maschinen, da unmittelbar nach dem Arbeitsgang der Färbe- und der Wischvorrichtung der Arbeitsgang des Stempels beginnen kann.ίο staining and wiping device under the Bringing the stamp, and the operation of inking and wiping the stamp. When the car is idle, the stamp is also in place as it is during the work cycle quiet. This affects the performance of the machine. At the device According to the present invention, this disadvantage is avoided in that the support of the dyeing and wiping device executes a circular motion, with the inking brush in is pushed back and forth in the axial direction. A blank, meanwhile the stamp having to remain inactive is thus avoided. Under otherwise identical working conditions would be a machine equipped with the apparatus of the present invention achieve twice the performance than the machines provided with the already known devices, because immediately after the operation of the dyeing and wiping device, the operation of the stamp can begin.

In einem Ständer 1 ist die Antriebswelle 2 gelagert. Sie trägt an ihrem vorderen Ende eine Kurvenscheibe 3 zur zwangläufigen Bewegung des den Prägestempel 4 tragenden Preßschlittens 5. Auf der Welle 2 sitzt außerdem noch ein Kegelrad 6, das mit einem anderen Kegelrad 7 in Eingriff steht. Von den beiden Kegelrädern ist das Rad 6 nur auf der Hälfte des Umfanges mit Zähnen versehen, so daß das Rad 7 nur während einer halben Umdrehung des Rades 6 gedreht wird, während der anderen halben Umdrehung aber stehenbleibt. Die Zähnezahl der beiden Kegelräder ist so bemessen, daß das Rad 7 während seines Eingriffes mit dem Rad 6 eine ganze Umdrehung macht. Das Kegelrad 7 treibt eine Welle 8, die in dem Ständer 1 gelagert ist und an ihrem unteren Ende ein Segment 9 trägt, auf dem die Färbe- und Abwischvorrichtung angeordnet ist. Die Färbevorrichtung besteht aus einer Bürste 10, die mit Zapfen 11 und 12 in dem Farbkasten 13The drive shaft 2 is mounted in a stand 1. She wears on her front end a cam 3 for the inevitable movement of the die 4 carrying the die Press slide 5. On the shaft 2 also sits a bevel gear 6, which with a other bevel gear 7 is engaged. Of the two bevel gears, the wheel is only 6 provided with teeth on half of the circumference, so that the wheel 7 rotates only during half a revolution of the wheel 6 but stops during the other half turn. The number of teeth of the two Bevel gears is dimensioned so that the wheel 7 during its engagement with the wheel 6 a makes a full turn. The bevel gear 7 drives a shaft 8 which is mounted in the stator 1 is and at its lower end carries a segment 9 on which the dyeing and wiping device is arranged. The staining device consists of a brush 10 which with pins 11 and 12 in the paint box 13

Claims

is rotatably mounted. The pin ii carries a crank arm 15 provided with a pin 14. This pin 14 engages in the slot 16 of one arm 17 of a two-armed lever which has its pivot point at 18. The other arm ig of the two-armed lever carries at its end a roller 20 which runs in a curved path 21 when the segment 9 is rotated. The pin 14 also carries a disk 22 against which a compression spring 23 rests. The other end of the compression spring sits on the arm 17 of the two-armed lever and thus presses the pin 14 and thus the brush in the direction of the arrow 29. In addition, the pin 14 still encounters a stop 24 located in its path during its movement Elevations and depressions are provided roughly in the manner of a ratchet wheel. The paint box 13 together with the brush 10 is expediently set up so that it can be removed so that different colors can be used. The wiping device is arranged directly behind the dyeing device. This consists of a leather strip 26 which is arranged on the segment 9 so as to be exchangeable. . The cleaning device arranged on the frame 1 is used to remove the ink removed from the embossing stamp on the leather strip 26. This is ordered from a felt strip 27 which protrudes from a container 28 filled with gasoline or a similar, paint-dissolving liquid. When the wiper 26 is rotated, it passes under the felt strip 27, the latter removing the paint adhering to the wiper 26 therefrom. The device works as follows: When the teeth of the bevel gear 6 mesh with the teeth of the bevel gear 7, the shaft 8 and thus the segment 9 are rotated in the direction of the arrow 30. Here, the roller 20 of the two-armed lever 17, 18, 19 comes into the curved track 21 and is moved upwards. The lever 17 is pressed downwards and with it the crank arm 15. As a result, the brush 10 is rotated upwards, whereby it stands horizontally. This horizontal position is completed at the moment when the brush 10 comes to the die 4. At the same time, the pin 14 strikes the stop 24 and slides onto one of the raised areas arranged in the radial direction. The pin 14 is pressed radially outwards and with it the brush 10. Once the pin 14 has slid over the elevation, the spring 23 presses it into the recess of the stop 24 following the elevation, and the brush 10 makes the movement in the radial direction back again. This process is repeated as long as the pin 14 slides over the stop 24. The position of this stop 24 depends on the length of the die 4, as does the cam groove 21. If the brush 10 moves past the die 4, the roller 20 slides into the downward part of the cam groove 21, the lever arm 19 is down moves, the lever arm 17 up, and with the mediation of the pin 14 and the crank arm 15, the brush 10 is rotated down into its rest position in the paint box 13. This rest position must be established when the cleaning device 27, 28 is reached. Immediately after the embossing stamp 4 has been colored, the leather strip 9 of the wiper strips off the excess color from the stamp. As the movement continues, the wiper 26 comes under the cleaning device 27, and the latter removes the ink that has been wiped off by the die 4 again from the wiper. Patents T-A ν claims:

1. Embossing press with fixed die and one under the die carrier moved past for the dyeing and wiping device, characterized in that that the carrier (9) performs a circular motion.

2. embossing press according to claim 1, characterized in that the inking of the die (4) providing brush (10) with the mediation of a her connected, sliding over elevations and depressions of a stop (24) Pen (14) moved back and forth in the axial direction during the inking will.
